I came across a well-researched and informative blog today summing up the recent findings and YDB science to date. I was so impressed by Abby Tabor’s post at Science Works Now, “New Evidence for Climate-Changing Cosmic Impact,” I have added a permanent link to her on the side-bar.
Tabor it seems was driven — shudder — [...]
These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H.

Distinguished Science writer Dr. Richard Kerr walked the plank this afternoon in response to this morning’s Knight Science Journalism Tracker inquiry of science writers.
Charles Petit’s casual post brought quick attention from the old-school dean of science writing. Kerr implored his press colleagues to, in effect: Move on, move on…There is nothing to see here.
Well, well. A cat just leapt from the bag.
I don’t have an “as published” copy yet (despite being a co-author). But I will post one just as soon as I do.

The PNAS paper has a helpful bibliography of recent publications supportive of the hypothesis. It’s worth a separate block quote below.
Nice how the links take you to the cites themselves at the PNAS website.

“If this were the first paper I would have taken it seriously.”
